When cross-compiling QtMobility within Yocto I noticed an interesting issue with Pseudo. It was obvious that QDir::canonicalPath wasn't working as expected which after further digging led to realisation that realpath isn't working for the realpath(path, NULL) case at least. This broke all of Qt's tools (qmake, moc) in certain use cases. I verified this to be problem when PSEUDO_DISABLED is 1 with the attached trivial test case. Compiling and running the test normally without pseudo (works fine): uusirant@4fiw00588:~/tmp$ gcc test_realpath.c -o test_realpath uusirant@4fiw00588:~/tmp$ ./test_realpath Returned path: /usr Expected.....: /usr ---- Here's how it looks with PSEUDO_DISABLED=0 (works fine): uusirant@4fiw00588:~/tmp$ PSEUDO_DISABLED=0 ../pseudo-install/bin/pseudo pseudo: Warning: PSEUDO_PREFIX unset, defaulting to /home/uusirant/pseudo-install. root@4fiw00588:~/tmp# gcc test_realpath.c -o test_realpath root@4fiw00588:~/tmp# ./test_realpath Returned path: /usr Expected.....: /usr --- And here's with PSEUDO_DISABLED=1 (realpath fails with EINVAL): uusirant@4fiw00588:~/tmp$ PSEUDO_DISABLED=1 ../pseudo-install/bin/pseudo pseudo: Warning: PSEUDO_PREFIX unset, defaulting to /home/uusirant/pseudo-install. uusirant@4fiw00588:~/tmp$ gcc test_realpath.c -o test_realpath uusirant@4fiw00588:~/tmp$ ./test_realpath realpath: Invalid argument 14228 1 mark.hatle 2011-06-09 08:55:36 +0000 Upstream author has confirmed the issue and a patch is pending. 14229 2 mark.hatle 2011-06-09 09:43:47 +0000 Fixed: http://git.yoctoproject.org/cgit/cgit.cgi/pseudo/commit/?id=c2f7c5ad8ef0f9c94a2a8382c109c8c6e16c8b18 Also verified by the original submitter.
